Question 1033137
The wheel had an angular velocity of 500 radians per minute. How fast was the wheel rolling along in kilometers per hour if the radius of the wheel was 170 centimeters?
===============
500 rad/min = 500/2pi rev/min
---
Each rev is the perimeter = 2*pi*170 cm
340pi*(500/2pi) = 85000 cm/min = 0.85 km/min
0.85 km/min * 60 min/hr = 51 km/hr
